Stupid Airsoft installs a Titanium Zet plate upgrade for the Double Eagle N4 MWS airsoft rifle. This specific modification addresses an issue where the bolt travels too far back into the buffer tube, potentially causing damage. By swapping the standard plate for a lighter titanium version, the user ensures the bolt catches more reliably and requires less gas pressure to operate.

The process involves a fairly straightforward disassembly of the rifle's lower receiver. After removing the magazine and body pins, Stupid Airsoft takes out the mag release, fire selector, and the entire trigger box. A bit of lighthearted tension arises during the removal of these parts, as losing a tiny spring or detent is a classic hazard of airsoft maintenance, but the components luckily remain accounted for.

Once the new titanium plate is seated and the rifle is reassembled, a quick test confirms that the bolt locks back correctly on an empty magazine. He suggests that this upgrade is beneficial even for stock setups because it improves the overall efficiency of the gas system. The project concludes with a functioning rifle and a hint at future cosmetic changes to the front end of the build.
